This adds Gerrit 3.11 image builds an a system-config-run job for a 3.11
deployment. We don't add 3.10 to 3.11 upgrade testing yet. This will
happen as a followup once we're happy with general image building and
testing.
This adds explicit push and force push permissions to the Administrators
group via code reviewed changes. The reason for this is Gerrit 3.11 has
decided that everything should be code reviewed by default including
actions by Administrators. Since we're just doing this for bootstrapping
of testing we quickly add the old expected permissions back via code
review.
This has a side effect of bumping up the change numbers for the cahnges
we care about in review up by 2 integer values. The tests and
screenshots are all updated to accomodate the shift in change numbers.
